================

[](#phpmettlertoledo)

A PHP Library for network communication with Mettler Toledo balances and scales that use the Mettler Toledo Standard Interface Command Set (MT-SICS). This works is based on [repo atlantis-software/mt-sics](https://github.com/ricado-group/dotnet-mettlertoledo)and [repo ricado-group/dotnet-mettlertoledo](https://github.com/ricado-group/dotnet-mettlertoledo)

} else {
    $error = $scale->getError()
}
```

### Unit Testing (without hardware)

[](#unit-testing-without-hardware)

As of v2.0.0, you can use dependency injection to test your code without requiring a physical scale:

```
use PhpMettlerToledo\MTSICS;
use PhpMettlerToledo\SICS\ExecuteCommandInterface;

// Create a mock for testing
$mockExecuteCommand = $this->createMock(ExecuteCommandInterface::class);
$mockExecuteCommand->method('readNetWeight')->willReturn(123.45);

// Inject the mock
$scale = new MTSICS('192.168.1.100', 4305, $mockExecuteCommand);
$weight = $scale->readNetWeight(); // Returns 123.45
```

### Integration Testing (with hardware)

[](#integration-testing-with-hardware)

To run integration tests with a physical scale, update the IP address in `tests/PhpMettlerToledo/CommandTest.php` and run:

```
vendor/bin/phpunit tests/PhpMettlerToledo/CommandTest.php
```

Note: `CommandTest.php` is excluded from the default test suite as it requires physical hardware.

Upgrade Guide
-------------

[](#upgrade-guide)

### From v1.x to v2.0

[](#from-v1x-to-v20)

- Upgrade your PHP version to 8.1 or higher, OR
